21 Jul 2006 An ester is produced when an organic acid reacts with an alcohol in a reaction called esterification. In the synthesis.

Lab 1: Synthesis - The University of Akron

Esters are produced by the reaction between alcohols and carboxylic acids For example reacting ethanol with acetic acid to give ethyl acetate is shown below ? In the case of ethyl acetate R1 is a CH3 group and R2 is a CH3CH2 group Naming esters systematically requires naming the functional groups on both sides of the bridging oxygen

Experiment 13 What’s That Smell? (Synthesis of Esters)

Esters are readily prepared from the condensation reaction of a carboxylic acid and an alcohol catalyzed by the addition of a strong acid such as sulfuric acid This reaction is described as: O ROH+HOCR' R OCR'+ H2O alcohol carboxylicesteracid Two examples are shown below: CH3CH2OH ethanol CH3 OH + methanol HOCCH3 ethanoicacid HOCCH2CH3

Experiment 18 — Synthesis of Esters - Amherst

The most common method for preparing esters is acid-catalyzed reaction of a carboxylic acid and an alcohol a process known as Fischer esterification The reaction is reversible and requires excess reactant and/or removal of water to drive it to completion
